It's the most powerful XJ ever built.

In an effort to reinvigorate one of its oldest offerings – the XJ has been on the market in its current form since 2009 – Jaguar has decided to spruce up the large sedan with a special performance designation. The Jaguar XJR575 is the most powerful, quickest production XJ the company has ever built, and it made its world debut back in July.

Update:

Under the hood of the hot XJ is a 5.0-liter V8 producing 575 supercharged horses (422 kilowatts) and 516 pound-feet (700 Newton-meters) of torque, up from the 550 hp (410 kW) a 502 lb-ft (680 Nm) of torque found on the previously most-powerful XJ R. That type of power allows it to sprint to 62 miles per hour (100 kilometers per hour) in just 4.4 seconds, and on to 186 mph (299 kmh) in just 44 seconds.


Apart from the more powerful engine, the XJR575 also adds on some a few special performance features to the exterior. Two bespoke exterior finishes created by Jaguar’s Special Vehicle Operations division – Velocity Blue and Sating Corris Grey – can be had at no extra cost. Twin louvres on the hood, 20-inch Farallon gloss-black wheels, and tailor-made details on the rear spoiler, side sills, front bumpers, and lower air intakes finish off the aggressive look.

In the cabin, a number of luxurious fixtures have also been added. Upgrades to the Touch Pro Infotainment system include a larger 10-inch touchscreen and 4G Wi-Fi, while black diamond-stitched leather with red stitching accents, including the "575" moniker emblazoned on the seat backs, covers the seats and dash.

The XJR575 will be built at Jaguar Land Rover’s Castle Bromwich plant alongside the XE, XF, F-Type, and the rest of the XJ range. The 575 performance model gains a slight price bump over the less-powerful R, which started at $118,995. The XJR575 can be had for $122,400 in the U.S. when it goes on sale in just a few weeks.
